Referring to fig. 1 to 5, an embodiment of the present disclosure provides a stocker including a transfer robot and a transfer box 1. Wherein the transfer robot is configured to transfer the tote 1. Illustratively, the transfer robot may include a chassis (not shown), a mast (also referred to as a column, not shown), and a box handling device 2. Wherein, the portal sets up on the chassis, gets case device 2 and sets up on the portal.

Specifically, in the embodiment of the present application, the chassis may be the same as or similar to the chassis in the related art, and will not be described herein. The door frame can be fixedly arranged on the chassis and driven by the chassis to move, wherein the connection mode of the door frame and the chassis can be the same or similar to the mode in the related art, and the embodiment of the application is not repeated.

In addition, it can be understood that a communication module can be arranged on the chassis or the portal frame, and the communication module can communicate with the upper computer and receive a control signal sent by the upper computer; in addition, the communication module can upload the position information of the transfer robot to the upper computer, and the upper computer controls the transfer robot to move in the warehouse system according to the transfer task, for example, to the target carrier so as to be convenient for docking with the target cargo space in the target carrier, thereby realizing the box taking or box returning process.

The box taking device 2 is arranged on the portal and can move up and down along the portal, for example, a lifting mechanism can be arranged on the portal, the box taking device 2 is arranged on the lifting mechanism, the lifting mechanism can move up and down along the portal, and after the transfer robot moves to the target carrier, the lifting mechanism can drive the box taking device 2 to move up and down along the portal, so that the height (namely the designated position) of the goods space where the corresponding turnover box 1 is located is reached.

In some examples, the transfer robot further comprises: temporary storage plate and rotary mechanism.

The temporary storage plate is arranged on the portal, the rotating mechanism is connected with the box taking device 2, and the rotating mechanism is configured to drive the box taking device 2 to rotate, so that the box taking device 2 stores the turnover box 1 on the temporary storage plate, or the turnover box 1 is taken out from the temporary storage plate through the box taking device 2.

It will be appreciated that the box taking device 2 may be located on one side of the gantry, with the temporary storage plate being located on the other side of the gantry; in some examples, the temporary storage plate may be provided in plurality along the height direction of the mast, or in some understandings it may be understood that the temporary storage plate is provided in plurality of layers along the height direction of the mast. Like this, transfer robot can carry a plurality of turnover boxes 1 once, has promoted the transfer efficiency of turnover box 1.

In some examples, the driving structure on the portal may be connected to a lifting mechanism, where the lifting mechanism is driven by the driving mechanism to lift, and a rotating mechanism is disposed on the lifting mechanism, where the rotating mechanism is connected to a base of the box taking device 2, and the base may rotate relative to the lifting mechanism, so as to drive the box taking device 2 to rotate.

The turnover box 1 is used as a carrier for transporting cargos, namely the transported cargos can be placed in the turnover box 1, so that the transported cargos can be placed in the turnover box 1, and the transfer rate of the transported cargos is quickened by the transfer robot through the transportation of the turnover box 1. The transfer box 1 may thus also be referred to as a logistics box.

Illustratively, the tote 1 can include a first side plate 11 disposed opposite in a first direction and a second side plate 12 disposed opposite in a second direction, the first direction intersecting, e.g., perpendicular, the second direction. The two first side plates 11 and the two second side plates 12 together enclose a frame body that accommodates goods. It will be appreciated that the cavity inside the frame, i.e. the frame cavity 1a, is for receiving cargo.

Referring to fig. 2-5, in some examples, the box handling device 2 includes a housing 21 and a box handling structure 22, the box handling structure 22 being extendable or retractable relative to the housing 21 for movement between the interior cavity of the housing 21 and a target cargo space, the box handling structure 22 being configured to act on the tote 1 and to move the tote 1 between the interior cavity of the housing 21 and the target cargo space. For example, in the case taking process, the case taking structure 22 extends out of the case 21 and reaches the target cargo space, then the case taking structure carries the turnover case 1 back into the inner cavity of the case 21, the case taking process is realized, and finally the turnover case 1 is transferred to the next link, such as a picking workstation, through the transfer robot. Or in the box returning process, the box taking structure 22 carries the turnover box 1 to extend to the target goods position, and transfers the turnover box 1 to the target goods position to realize the box returning process.

In practice, the box taking structure 22 has various structures, and box taking manners of the various structures are different, so that types of the transfer robot are diversified, for example, the box taking structure 22 of the transfer robot includes at least one of a first box taking structure, a second box taking structure and a third box taking structure. Illustratively, the transfer robots are classified into a first transfer robot, a second transfer robot, and a third transfer robot according to the types of the transfer robots, wherein the box taking structure 22 of the first transfer robot is a first box taking structure, the box taking structure 22 of the second transfer robot is a second box taking structure, and the box taking structure 22 of the third transfer robot is a third box taking structure.

It can be appreciated that the first box taking structure, the second box taking structure and the third box taking structure are different in box taking modes.

Referring to fig. 2 and 3, for example, the first box taking structure acts on the front end surface of the turn-around box 1, such as any one of the first side plates 11, at the time of box taking, to reduce the space occupied by the box taking structure 22 on the side of the turn-around box 1, so that the storage density of the pallet for storing the turn-around box 1 can be improved. For example, the first box taking structure may be a suction cup structure 221, the suction cup structure 221 being configured to suck the front end surface of the transfer box 1, for example, by controlling the vacuum degree in the suction cup structure 221, to achieve suction and release of the front end surface of the transfer box 1. Illustratively, when the box is taken, after the sucker structure 221 adsorbs the turnover box 1, the turnover box 1 is carried back into the inner cavity of the housing 21, and when the box is returned, the sucker structure 221 adsorbs the turnover box 1 and carries the turnover box 1 to move to the target cargo space.

In some examples, the suction cup structures 221 may not need to adsorb the tote 1 when returning to the box, and the tote 1 may be pushed to the target cargo space by pushing the tote 1 when forgetting to move to the target cargo space via the suction cup structures 221.

In some examples, the first box taking structure may also be an electromagnet, and accordingly, the front end surface of the turnover box 1 may be specifically made of a material (for example, iron material) that can be absorbed by the magnet, and when the turnover box 1 is taken back, the electromagnet may be powered up when the electromagnet is close to or in contact with the turnover box 1, so that the magnetic attraction force of the electromagnet on the turnover box 1 provides a carrying force on the turnover box 1.

It will be appreciated that in other possible examples of embodiment of the application, the first box taking structure may be made of a material that can be attracted by a magnet, and accordingly, an electromagnet is disposed on the front end face of the turnover box 1; so, when getting still to turnover case 1, can be when first case structure and turnover case 1 are close to or contact to the electro-magnet, power on to make first case structure and the electro-magnet on the turnover case 1 of getting between produce the magnetic attraction, thereby provide the transport power to turnover case 1.

Referring to fig. 4, the second box taking structure may act on a side surface (for example, the second side plate 12) of the turnover box 1 when taking the box, for example, the second box taking structure may be a fork holding structure 222, where the fork holding structure 222 includes two telescopic forks 2221 disposed at intervals. The telescopic fork 2221 is configured to clamp the side surface of the turn-around box 1, for example, two second side plates 12, and the telescopic fork 2221 can be extended or retracted in the picking and placing direction to move the turn-around box 1 between the inner cavity of the housing 21 and the target cargo space. Illustratively, the telescoping fork 2221 may be a primary telescoping fork 2221 structure, a secondary telescoping fork 2221 structure, or a more numerous number of telescoping fork 2221 structures to select according to the actual box removal stroke.

In some examples, the clasping fork structure 222 may further include a pulling finger 2222, where the pulling finger 2222 is movably disposed at least one end of the telescopic fork 2221, and the pulling finger 2222 may rotate to a clamping cavity between two telescopic forks 2221, so as to assist the telescopic fork 2221 to apply a force to an end surface of the turnover box 1, so as to drive the turnover box 1 to move along the picking and placing direction.

For example, the fingers 2222 may include front fingers (shown with reference to fig. 4) that may be provided with front ends (ends near the target cargo space) of telescoping forks 2221 that are movable between a vertical position and a horizontal position. In the box taking process, when the two telescopic forks 2221 extend towards the turnover box 1, the front poking fingers are kept at vertical positions so as to ensure that the turnover box 1 smoothly enters between the two telescopic forks 2221; when the two telescopic forks 2221 extend to the two second side plates 12 of the turn-around box 1, the front fingers move and remain in a horizontal position to be stopped on the rear end surface of the turn-around box 1, for example, one of the first side plates 11; when the two telescopic forks 2221 are retracted in the pick-and-place direction, the front fingers act on the first side plate 11 of the rear end of the turn-around box 1 and retract the turn-around box 1 into the inner cavity of the housing 21.

For another example, the fingers 2222 may further include a rear finger (also referred to as a rear push rod), which may be disposed at a rear end of the telescopic fork 2221 (an end far away from the target cargo space), where the rear finger is located in the clamping cavities of the two telescopic forks 2221, and the rear finger may assist in pushing the turnover box 1 forward when the two telescopic forks 2221 clamp the turnover box 1 to extend toward the target cargo space during the box returning process, so as to ensure that the turnover box 1 is smoothly transferred onto the target cargo space.

Referring to fig. 5, a third box-taking structure may act on one of the surfaces of the transfer box 1 to carry the transfer box 1 between the interior cavity of the housing 21 and the target cargo space. For example, the third box taking structure may be a clamping jaw structure 223, and the clamping jaw structure 223 may be hooked on one surface of the turnover box 1, for example, the first side plate 11, so as to drive the turnover box 1 to move.

It will be appreciated that in order to cooperate with the jaw arrangements 223, it is necessary to form hooking locations, such as holes or protrusions 15, on the surface of the transfer case 1, in which holes or protrusions 15 the jaw arrangements 223 are hooked to effect transfer of the transfer case 1. Wherein the jaw structure 223 may be a motorized jaw.

Based on the above, the structural stability of the corresponding side surface of the box taking structure 22 is required to be ensured no matter what box taking structure 22 is. For example, for the first box taking structure such as the suction cup structure 221, the front end surface of the turn-around box 1 such as the first side plate 11 needs to be stably in an upright state to ensure that the suction cup structure 221 stably acts on the first side plate 11. Or for the second box taking structure, such as the clasping structure 222, the two first side plates 11 of the turnover box 1 need to be stably in an upright state so as to ensure that the front fingers and the rear fingers stably act on the first side plates 11 to push or pull the turnover box 1.

However, the upright wall type transfer case 1 is large in volume, occupies a large space during the empty transportation (i.e., no cargo in the inner cavity of the transfer case 1), so that the transfer case 1 for one-time transportation of transportation vehicles such as vehicles is small, and the transportation cost and the purchase cost of the transfer case 1 are increased.

Accordingly, the embodiment of the present disclosure provides a transfer case 1, which is configured to be foldable to reduce the occupied space during the air transportation, and to reduce the transportation cost and the purchase cost. In addition, by supporting one of the side plates of the transfer box 1 in the upright state on the other side plate, the structural stability of the one of the side plates in the upright state is increased, so that the stability of the cooperation of the transfer robot acting on the first side plate 11 with the transfer box 1, for example, the stability of the cooperation of the first box taking structure such as the suction cup structure 221 and the second box taking structure such as the holding fork structure 222 of the transfer robot with the transfer box 1, is improved, and the transfer efficiency of the box taking structure 22 to the transfer box 1 is improved.

Fig. 6 is a schematic view of the case 1 provided in an embodiment of the present application in an intermediate folded state, and fig. 7 is a schematic view of the case 1 provided in an embodiment of the present application after being fully folded. Referring to fig. 1, 6 and 7, the turn-around box 1 of the embodiment of the present application may include a base 13, two opposite first side plates 11 and two opposite second side plates 12; the two first side plates 11 are arranged along the first direction X, and the two second side plates 12 are arranged along the second direction Y; both the two first side plates 11 and the two second side plates 12 are movably connected with the base 13.

In this way, the first side panel 11 and the second side panel 12 can move relative to the base 13, i.e. both the first side panel 11 and the second side panel 12 can be folded relative to the base 13; so that the turn-around box 1 can be folded. Illustratively, the first and second side plates 11, 12 are rotatably coupled with respect to the base 13 such that the first and second side plates 11, 12 are rotated onto the base 13. In some examples, the first side panel 11 and the second side panel 12 may also be detachably connected to the base 13, and when folding is required, the first side panel 11 and the second side panel 12 may be directly detached from the base 13 and folded onto the base 13. The folded container 1 has a smaller size in a direction crossing (e.g., perpendicular) the base 13, i.e., in a height direction (also referred to as a gravity direction) of the container 1, so that the folded container 1 has a smaller size, thereby reducing the air transportation cost of the container 1 and the purchase cost of the container 1. Wherein the first direction X intersects (e.g., is perpendicular to) the second direction Y.

Illustratively, the first side panel 11 and the second side panel 12 are detachably connected such that the first side panel 11 and the second side panel 12 are respectively foldable and unfoldable in sequence.

For convenience of description, embodiments of the present disclosure also provide a third direction Z that intersects the first direction X (e.g., perpendicular) and intersects the second direction Y (e.g., perpendicular), i.e., the third direction Z may be regarded as the height direction of the turn-around box 1; in the case where the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, the first direction X, the second direction Y, and the third direction Z may constitute a three-dimensional coordinate system. The first direction X, the second direction Y, and the third direction Z may constitute a three-dimensional coordinate system.

When the turnover box 1 is in the folded state, the two second side plates 12 and the two first side plates 11 are both located on the base 13, for example, the two second side plates 12 are located between the two first side plates 11 and the base 13, in other words, the two first side plates 11 are located above the two second side plates 12 along the third direction Z, for example, during the folding process of the turnover box 1, the two second side plates 12 can be folded one by one toward the base 13, and then the two second side plates 12 can be folded one by one toward the two second side plates 12, so as to reduce the height of the turnover box 1 along the third direction Z, thereby reducing the occupied space of the turnover box 1 during the air transportation process.

When the turnover box 1 is in an upright state, the two first side plates 11 and the two second side plates 12 jointly enclose a frame body for containing goods, and a goods taking and placing opening of the frame body is arranged opposite to the base 13, for example, is positioned at the upper part of the turnover box 1 along the third direction Z. The first side plates 11 are supported on the second side plates 12, and illustratively, two inner surfaces of the first side plates 11 along the second direction Y are respectively supported on the ends of the two second side plates 12, so as to improve the structural stability of the first side plates 11 in the upright state of the turnover box 1.

Referring to fig. 1, the base 13 illustratively includes a main body, and two opposing first mounting portions 131 and two opposing second mounting portions 132. The two first mounting portions 131 are arranged along the first direction X; the two second mounting portions 132 are arranged in the second direction Y. The two first mounting parts 131 and the two second mounting parts 132 are fixedly connected with the main body; for example, the two first mounting portions 131, the two second mounting portions 132, and the main body are integrally formed. The first side plate 11 is rotatably provided on the first mounting portion 131, and the second side plate 12 is rotatably provided on the second mounting portion 132.

Since the turn-around box 1 of the embodiment of the present disclosure can be folded, the turn-around box 1 has a folded state and an upright state. I.e. in the folded state, the transfer container 1 is relatively low cost when transported. In the upright state, the turnover box 1 can be used as a carrier to place cargoes into the turnover box 1, so as to achieve the purpose of transporting the cargoes.

The first side panel 11 is separated from the second side panel 12 when the transfer case 1 is in the folded state. Both second side plates 12 are in contact with the base 13; that is, the two second side panels 12 and the two first side panels 11 are folded onto the base 13. Thus, compared with the vertical type turnover box 1, the turnover box 1 is smaller in size in the third direction Z in the folded state, so that the volume of the turnover box 1 is reduced, and the empty transportation cost and the purchasing cost of the turnover box 1 are further reduced.

Illustratively, the two first side panels 11 may be attached to the entirety of the two second side panels 12; that is, in the folded state, the two first side plates 11 may be in contact with the entirety of the two second side plates 12; that is, in the third direction Z, the entirety of the two first side plates 11, the entirety of the two second side plates 12, and the base 13 are stacked in this order. In some examples, the first mounting portion 131 has a dimension that is greater than a dimension of the second mounting portion 132 in the third direction Z, such as a dimension between the first mounting portion 131 and the second mounting portion 132 that is greater than or equal to the thickness of the second side plate 12. In this way, the two first side plates 11 can be fitted to the entirety of the two second side plates 12 relatively horizontally.

Also illustratively, the base 13 has opposite front and back sides (e.g., the back side may also be referred to as the bottom side, the front side may also be referred to as the top side, when the base 13 is placed on the ground), and the two second side plates 12 are attached to the front side of the base 13; the two first side plates 11 may be attached to the back surface of the base 13. That is, in the third direction Z, the entirety of the two second side plates 12, the entirety of the base 13, and the entirety of the two first side plates 11 are stacked in this order.

With continued reference to fig. 1, when the transfer case 1 is in an upright state, the two first side plates 11 and the two second side plates 12 enclose a frame; that is, one first side plate 11, one second side plate 12, the other first side plate 11, and the other second side plate 12 are enclosed in this order to form a frame. The frame body is provided with an opening opposite to the base 13, so that goods can be placed into the turnover box 1 through the opening. The two second side plates 12 are located between the two first side plates 11, and the second side plates 12 function to support the two first side plates 11 when the first side plates 11 are engaged with the box taking structure 22 of the transfer robot.

In this context, the outer surface of the first side plate 11 may be understood as the surface of the first side plate 11 facing away from the interior of the frame, and the inner surface of the first side plate 11 may be understood as the surface of the first side plate 11 facing towards the interior of the frame, wherein the outer surface of the first side plate 11 is opposite to the inner surface of the first side plate 11. The outer and inner surfaces of the second side plate 12, and the outer and inner surfaces of the second side plate 12 may be understood with reference to the relevant descriptions of the outer and inner surfaces of the first side plate 11.

When the transfer box 1 of the embodiment of the present application is matched with a transfer robot, the first side plate 11 and the second side plate 12 of the transfer box 1 can be used as side plates which are used for taking and returning the box, in other words, the transfer robot can selectively act on the first side plate 11 and/or the second side plate 12 when taking and returning the transfer box 1, and specifically, the selection of the acting side plates can be performed according to different box taking modes of the box taking structure 22 of the transfer robot. For example, the box taking structures 22 of at least three types of transfer robots can be matched with different side plates, so that transfer robots of different types can transfer the transfer box 1, and the adaptability of the transfer box 1 to multiple types of transfer robots is improved. Illustratively, the first side plate 11 is configured to cooperate with the first and second box-taking structures, and the second side plate 12 is configured to cooperate with the second and third box-taking structures, so that the transfer box 1 is transported under the influence of the transfer robot.

That is, the first box taking structure acts on the first side plate 11 of the turn-around box 1 to carry the turn-around box 1 to move. For example, the suction cup structure 221 sucks the first side plate 11 of the turn-around tank 1 to carry the turn-around tank 1 for movement. The first box taking structure can act on any one first side plate 11 of the two first side plates 11.

The third box taking structure acts on the second side plate 12 of the turnover box 1 to carry the turnover box 1 to move. For example, the jaw structure 223 is hooked to the second side plate 12 to carry the transfer case 1 for movement. Illustratively, a boss 15 may be provided on the second side plate 12, and the jaw structure 223 is clamped to the boss 15 to carry the tote 1 for movement. Of course, a slot or a jack may be formed on the second side plate 12, and the clamping jaw structure 223 is inserted into the slot or the jack and abuts against a cavity wall of the slot or the jack, so as to provide a carrying capacity for the turnover box 1 and drive the turnover box 1 to move. The clamping jaw structure 223 may include two clamping jaws, which are respectively clamped on the two second side plates 12, so as to improve the stability of the acting force on the turnover box 1.

The second box taking structure acts on the first side plate 11 and the second side plate 12 of the turnover box 1 to carry the turnover box 1 to move. For example, the second box taking structure is a holding fork structure 222, a telescopic fork 2221 of the holding fork structure 222 and a poking finger 2222 arranged at the end part of the telescopic fork 2221, wherein the telescopic fork 2221 acts on the second side plate 12 to clamp the turnover box 1, the poking finger 2222 acts on the first side plate 11 to assist the telescopic fork 2221 to drive the turnover box 1 to move along the taking and returning direction, for example, two telescopic forks 2221 act on the two second side plates 12 respectively to clamp the turnover box 1, when the two telescopic forks 2221 extend to the two second side plates 12 of the turnover box 1, the front poking finger in the poking finger 2222 is kept in a horizontal position to block the rear end surface of the turnover box 1, for example, on the first side plate 11 at the rear end in the first direction X, and when the two telescopic forks 2221 retract along the taking and returning direction, the front poking finger acts on the first side plate 11 at the rear end of the turnover box 1 and returns the turnover box 1 to the inner cavity of the casing 21.

When the two telescopic forks 2221 clamp the turnover box 1 and extend towards the target cargo space, the rear poking fingers (also called rear push rods) in the poking fingers 2222 assist in pushing the turnover box 1 to move forward so as to ensure that the turnover box 1 is smoothly transferred onto the target cargo space.

Illustratively, a finger 2222 may be disposed at the front end or the rear end of each telescopic fork 2221, and two fingers 2222 disposed at one end of two telescopic forks 2221 may act on two areas of the first side plate 11 of the turnover box 1 along the second direction Y, respectively, so as to increase the mating area with the first side plate 11 of the turnover box 1 and improve the acting force on the turnover box 1. For example, the front fingers may have two, and the rear fingers may have two.

It can be understood that the turnover box 1 according to the embodiment of the present application can implement the box taking structure 22 of three different box taking modes, that is, different types of transfer robots can transfer the turnover box 1, thereby improving the applicability of the turnover box 1 according to the embodiment of the present application and further reducing the purchase cost of the turnover box 1.

In addition, by placing the first side plate 11 on the side of the second side plate 12 opposite to the base 13 in the folded state, the first side plate 11 is supported on the second side plate 12 in the upright state, so that the problem that the first side plate 11 is reversely buckled to the inner cavity 1a of the frame body when the first box taking structure or the second box taking structure pushes the box or the box is avoided, for example, the situation that the first side plate 11 is unstable and inclines downwards to the inner cavity 1a of the frame body when the first side plate 11 is pushed to the target cargo space by the sucking disc structure 221 can be avoided, or the situation that the finger 2222 of the fork holding structure 222 acts on the first side plate 11 on the rear side of the turnover box 1, when the turnover box 1 is pulled back, the situation that the first side plate 11 is abutted to the inner side of the frame body, or the first side plate 11 acts on the front side of the turnover box 1 when the turnover box 1 is pushed to advance, the situation that the first side plate 11 is pushed to the inner cavity 1 is improved, the stability of the first side plate 11 in the upright state is ensured, the matching of the first box taking structure or the second box taking structure and the first box taking structure is improved, and the stability of the first box taking structure is improved.

Referring to fig. 1, in some examples, at least one (e.g., one or two) of the first side panels 11 has a flattened area 114 on an outer surface (i.e., a side facing away from the interior cavity 1a of the frame) and a first tote structure, such as a suction cup mechanism, is capable of being sucked against the flattened area 114 to transfer totes 1 between the receiving cavity 21a of the housing 21 of the tote presentation device 2 and the target cargo space.

The flattening area 114 may be understood as that at least part of the outer surface of the first side plate 11 is a plane, which can improve or avoid the air leakage between the first side plate 11 and the suction disc structure 221 when the first side plate 11 is sucked, so as to ensure stable suction of the suction disc structure 221 to the first side plate 11.

Referring to fig. 1, in some embodiments, a plurality of reinforcing ribs 116 are disposed on the inner surface of the first side plate 11, where the plurality of reinforcing ribs 116 are at least partially disposed in a crossing manner, the plurality of reinforcing ribs 116 may enhance the strength of the first side plate 11, so as to improve or avoid deformation of the first side plate 11 when the first box taking structure, such as the suction cup structure 221, acts on the first side plate 11, thereby improving the stability of the acting force between the first box taking structure and the first side plate 11.

With continued reference to fig. 1, the first side plate 11 has a first reinforcing structure 115, where the first reinforcing structure 115 is configured to cooperate with the fingers 2222 of the yoke structure 222, for example, two first reinforcing structures 115 may be disposed on the first side plate 11, where the two first reinforcing structures 115 are arranged along the second direction Y, and the two fingers 2222 located at either end of the two telescopic forks 2221 act on the two first reinforcing structures 115 of the first side plate 11, so as to improve the structural strength of the cooperation position between the first side plate 11 and the fingers 2222, thereby improving or avoiding the occurrence of deformation of the first side plate 11 caused by long-term acting of the fingers 2222 of the yoke structure 222 on the first side plate 11.

In some examples, both first side panels 11 may have first reinforcing structures 115 thereon, wherein the first reinforcing structures 115 on one first side panel 11 (e.g., the first side panel 11 on the rear side) are configured to engage with the front fingers of the yoke structure 222 to avoid long term application of the front fingers to the first side panel 11 on the rear side, resulting in deformation of the first side panel 11 on the rear side, and the first reinforcing structures 115 on the other first side panel 11 (e.g., the first side panel 11 on the front side) are configured to engage with the rear fingers of the yoke structure 222 to avoid long term application of the rear fingers to the first side panel 11 on the front side, resulting in deformation of the first side panel 11 on the front side.

When the first reinforcing structure 115 is disposed beside the leveling region 114, for example, the leveling region 114 may be located between two first reinforcing structures 115, for example, the first reinforcing structure 115 may be located at an end region of the first side plate 11 near the second side plate 12, so as to increase the structural strength of the first side plate 11 at a region for matching with the second side plate 12, thereby ensuring the structural stability of the first side plate 11 relative to the second side plate 12, and avoiding the situation that the first side plate 11 is inclined inwards when the finger 2222 of the sucking disc structure 221 or the fork-holding structure 222 acts on the first side plate 11, so that the sucking disc structure 221 or the fork-holding structure 222 stably carries the turnover box 1 to move. For example, two first reinforcing structures 115 are respectively located on the outer surfaces of both ends of the first side plate 11 distributed along the second direction Y.

Wherein the first reinforcing structure 115 has a size of greater than or equal to 100mm (e.g., 100mm, 150mm, 200mm, etc.) in the height direction of the turn-around box 1, i.e., in the third direction Z, to secure the structural strength of the first side plate 11.

For example, when a pushing force of 150N is applied to the first reinforcement structure 115, the surface deformation amount of the first side plate 11 is less than or equal to 3mm (e.g., 3mm, 2mm, 1mm, etc.).

In some examples, the dimensions of the flattened region 114 in one of the second direction Y and the third direction Z are greater than or equal to 300mm, such as 300mm, 400mm, or 500mm, as appropriate, and the dimensions in the other are greater than or equal to 150mm, such as 150mm, 200mm, or 250mm, as appropriate. For example, the dimension of the flattened area 114 in the second direction Y is greater than or equal to (e.g., greater than, and for example, equal to) 300mm and the dimension in the third direction Z is greater than or equal to (e.g., greater than, and for example, equal to) 150mm. Also for example, the dimension of the flattened region 114 in the third direction Z is greater than or equal to (e.g., greater than, and such as equal to) 300mm and the dimension in the second direction Y is greater than or equal to (e.g., greater than, and such as equal to) 150mm.

Wherein, when a tensile force of 200N is applied to the first side plate 11 of the turnover box 1 at a position 150mm away from the base 133 (e.g., the bottom surface of the base 133) along the third direction Z, the surface deformation of the first side plate 11 is less than or equal to 5mm (e.g., 5mm, 4mm, 3mm, etc.), and when a pushing force of 200N is applied, the surface deformation of the first side plate 11 is less than or equal to 5mm (e.g., 5mm, 4mm, 3mm, etc.), so as to ensure that the sucker mechanism has little or no deformation when pushing or pulling the turnover box 1.

Referring to fig. 1 and 5, in order to ensure that the structural strength of the second side plate 12 is not affected when the third box taking structure, such as the clamping jaw structure 223, provides a force to the second side plate 12, the second side plate 12 may have a second reinforcing structure 123 thereon, where the second reinforcing structure 123 protrudes from the surface of the second side plate 12, and the clamping jaw structure 223 clamps on the second reinforcing structure 123, so as to improve or avoid deformation of the second side plate 12 caused by the clamping jaw structure 223.

Illustratively, the second reinforcing structure 123 may be provided at an end region of the second side plate 12 in the first direction X to increase the structural strength of the second side plate 12 at the region for cooperation with the first side plate 11, thereby ensuring structural stability of the second side plate 12 with respect to the first side plate 11, avoiding deformation of the second side plate 12 at the connection region with the first side plate 11 when the jaw structure 223 acts on the second side plate 12, so that the jaw structure 223 stably carries the turn-around box 1 for movement. For example, the second reinforcement structure 123 may be provided at either one of the both ends of the second side plate 12 distributed in the first direction X or at the outer surface of both ends, so that the direction of engagement of the turn-around tank 1 with the jaw structure 223 is not limited.

In some examples, the dimensions of the second reinforcing structure 123 in the third direction Z are each greater than or equal to 200mm, such as 200mm, 300mm, or 400mm, as appropriate, to enhance the structural strength of the second side plate 12 in cooperation with the jaw structure 223 to prevent deformation of the second side plate 12 when mated with the jaw mechanism.

In addition, the second reinforcing structure 123 protrudes from the second side plate 12 by a dimension greater than or equal to 15mm (for example, a suitable dimension of 15mm, 20mm, 25mm, etc.), that is, the dimension of the second reinforcing structure 123 along the second direction Y may be greater than or equal to 15mm, so as to increase the protruding degree of the second reinforcing structure 123, so that the clamping jaw mechanism is stably clamped on the second reinforcing structure 123.

For example, when a tensile force of 150N is applied to the second reinforcement structure 123, the surface deformation amount of the second side plate 12 is less than or equal to 3mm (e.g., 3mm, 2mm, 1mm, etc.).

In some examples, at least one of the first reinforcement structure 115 and the second reinforcement structure 123 may have a dimension along the height direction (i.e., the third direction Z) of the turn-around box 1 equal to the height of the turn-around box 1 in the erected state, for example, both ends of the first reinforcement structure 115 along the third direction may extend to the top and bottom of the turn-around box 1, respectively, to further enhance the structural strength of the first side plate 11 in the entire height direction, such that the deformation condition of the first side plate 11 is improved or avoided when the fingers 2222 of the suction cup structure 221 or the yoke structure 222 are engaged with the first side plate 11, or both ends of the second reinforcement structure 123 along the third direction may extend to the top and bottom of the turn-around box 1, respectively, to further enhance the structural strength of the second side plate 12 in the entire height direction, to ensure that the deformation condition of the second side plate 12 is improved or avoided when the jaw structure 223 is engaged with the second side plate 12.

Referring to fig. 1 and 4, in some examples, the second side plate 12 further includes a third reinforcing structure 124 thereon, and the third reinforcing structure 124 is configured to be embraced by the telescoping fork 2221 of the clasping fork structure 222. The third reinforcing structure 124 enhances the structural strength of the second side plate 12, and reduces the deformation of the second side plate 12 when the telescopic fork 2221 of the clasping fork structure 222 clasps the second side plate 12. The third reinforcing structure 124 may include a first beam, a second beam, and a reinforcing column, where the reinforcing column is located between and fixedly connected to the first beam and the second beam. The first and second beams extend in a first direction X and the reinforcement column extends in a third direction Z. The provision of the first and second cross members serves to connect the first and second cross members and also enhances the strength of the second side plate 12. When the number of the reinforcing columns is plural, the plurality of reinforcing columns are arranged along the first direction X. The second cross member is connected to the base 13 and the first cross member may be located on top of the second side plate 12.

Fig. 8 is a structural view of a first side plate 11 and a second side plate 12 in a view angle in the circulation box 1 according to an embodiment of the present application, fig. 9 is an enlarged view of fig. 8 at a, and fig. 10 is an enlarged view of fig. 8 at B. Referring to fig. 8 to 10, the first side plate 11 includes a first body portion 111 and a first connection portion 112 connected to the first body portion 111, and the first body portion 111 is configured to cooperate with a transfer robot, for example, the first body portion 111 has a flat area 114 or a first reinforcing structure 115. Illustratively, the first connection portion 112 may be located at an end of the first body portion 111.

The first body 111 is provided with a first fixing portion 113 on a side facing the housing cavity 1a, and the first fixing portion 113 is disposed opposite to the first connecting portion 112, for example, the first fixing portion 113 and the first connecting portion 112 may be disposed opposite to each other along the second direction Y.

In the upright state, the first connecting portion 112 is supported at the end of the second side plate 12, and a portion of the second side plate 12 is located between the first connecting portion 112 and the first fixing portion 113, for example, the first connecting portion 112 is supported at one portion of the end of the second side plate 12, and another portion of the end of the second side plate 12 is located between the first connecting portion 112 and the first fixing portion 113, so that the first connecting portion 112 and the first fixing portion 113 limit the rotation of the second side plate 12 and move along the second direction Y, and the stability of the second side plate 12 relative to the first side plate 11 is ensured.

The first connecting portion 112 may be detachably connected to the second side plate 12, so that the first side plate 11 is convenient to detach, and the first side plate is also limited to rotate. For example, a portion of the second side plate 12 is detachably connected to the first connecting portion 112. Wherein the detachable connection may be a snap connection, a bolt connection, or the like.

When provided, the first side plate 11 may include two first connection portions 112 and two first fixing portions 113. The first body portion 111 is located between the two first connection portions 112, and is connected to the two first connection portions 112. Two first fixing portions 113 are provided on the side of the first main body portion 111 facing the housing inner chamber 1 a; i.e. two first fixing portions 113 are fixed on the side of the first body portion 111 facing the housing interior 1 a. The two first connection portions 112 and the two first fixing portions 113 are each arranged along the second direction Y, and the two first fixing portions 113 are located between the two first connection portions 112. That is, in the second direction Y, one first connection portion 112, one first fixing portion 113, another first fixing portion 113, and another first connection portion 112 are sequentially arranged. The first body portions 111 of the two first side plates 11 are arranged in the first direction X. Thus, the plane of the first body 111 and the plane of the first connecting portion 112 intersect, and the angle of intersection is equal to the angle between the first direction X and the second direction Y.

In some examples, the first connecting portion 112 is in contact with the second side panel 12 and the first body portion 111 is not in contact with the second side panel 12 in the folded state. In other examples, the second side panel 12 has a receiving groove, and the first connecting portion 112 is placed in the receiving groove of the second side panel 12 in the folded state, and the first main body portion 111 may or may not be in contact with the second side panel 12.

Fig. 11 is a structural view of a first side plate 11 and a second side plate 12 in another view angle in the circulation box 1 according to an embodiment of the present application, fig. 12 is an enlarged view of fig. 11C, and fig. 13 is an enlarged view of fig. 11D. Referring to fig. 11 to 13, the second side plate 12 may exemplarily include a second body part 121 and a second connection part 122 connected to the second body part 121, for example, the second connection part 122 is located at an end of the second body part 121, and the second body part 121 and the second connection part 122 may be arranged in the first direction X. The second body 121 is configured to cooperate with the handling robot, for example, the second body 121 has a second reinforcing structure 123 and a third reinforcing structure 124, and the second body 121 may cooperate with a second box taking structure, for example, a clamping jaw structure 223, or may cooperate with a telescopic fork 2221 of the fork holding structure 222.

In the upright state, the second connecting portion 122 is located between the first connecting portion 112 and the first fixing portion 113; the first connection portion 112 is detachably connected (e.g., snap-fit connected) to the second connection portion 122. In addition, in some examples, the second body part 121 may have a mounting groove, and the first connection part 112 may be placed.

In some examples, the second side panel 12 may include a second body portion 121 and two second connection portions 122. The second body portion 121 is located between the two second connection portions 122, and is connected to the two second connection portions 122. The second body portion 121 and the two second connection portions 122 are arranged along the first direction X; the first connection portion 112, the second connection portion 122, and the first fixing portion 113 are sequentially arranged along the second direction Y.

In some examples, referring to fig. 9 and 10, one of the first and second connection parts 112 and 122 has a boss 15, and the other has a through hole 16. For example, the first connection portion 112 has a protruding portion 15, and the second connection portion 122 has a through hole 16; the boss 15 is located on a side of the first connecting portion 112 near the first fixing portion 113 at this time. For another example, the second connecting portion 122 has a protruding portion 15, and the first connecting portion 112 has a through hole 16; the boss 15 is located on a side of the second connecting portion 122 away from the housing. In the upright state, the protruding portion 15 is inserted into the through hole 16, so that the first connecting portion 112 and the second connecting portion 122 are in snap connection. The protruding portion 15 and the through hole 16 can bear a larger acting force between the first connecting portion 112 and the second connecting portion 122, so that the connection strength between the first connecting portion 112 and the second connecting portion 122 is increased, the first connecting portion 112 and the second connecting portion 122 are firmly connected, and the situation that the first side plate 11 is outwards stretched (inclined towards the direction opposite to the inner cavity 1a of the frame body) when the first box taking structure such as the sucker structure 221 adsorbs the turnover box 1 is prevented.

For example, the number of the protruding portions 15 is plural, and the plurality of protruding portions 15 are arranged in the third direction Z; accordingly, the number of through holes 16 is equal to the number of the protruding portions 15, and the plurality of protruding portions 15 and the plurality of through holes 16 are arranged in one-to-one correspondence.

In some examples, referring to fig. 12 and 13, a stepped surface 19 is formed between the second connection portion 122 and a side of the second body portion 121 facing away from the housing interior 1a, and it is understood that the stepped surface 19 is connected to an outer surface of the second body portion 121 and an outer surface of the second connection portion 122. The step surface 19 faces (e.g., in the first direction X) the first side plate 11; it will be appreciated that the stepped surface 19 is substantially parallel to the first body portion 111.

In the upright state, the first connecting portion 112 abuts against the step surface 19; in this way, the step surface 19 serves to support the first side plate 11, and the contact surface between the boss 15 and the through hole 16 also serves to support the first side plate 11; so that the forces acting on the second side plate 12 by the first side plate 11 are separated, extending the service life of the first side plate 11 and the second side plate 12.

The first connecting part 112 is flush with one side of the main body part facing away from the inner cavity 1a of the frame body; that is, the outer surface of the first connecting portion 112 and the outer surface of the second body portion 121 are flush, so that when the outer peripheral wall of the turn-around box 1 has an outward protruding structure, the outward protruding structure is easily collided with other structures, and the connection stability of each side plate of the turn-around box 1 is affected, and in addition, the frame body is more coordinated and attractive.

In some examples, referring to fig. 9 and 10, one of the first and second connection portions 112 and 122 has a positioning member 18 and the other has a positioning hole 17. For example, the first connecting portion 112 has a positioning member 18, and the second connecting portion 122 has a positioning hole 17; the positioning member 18 is located on a side of the first connecting portion 112 near the first fixing portion 113. For another example, the second connecting portion 122 has a positioning member 18, and the first connecting portion 112 has a positioning hole 17; the positioning member 18 is located on the outer side surface of the second connecting portion 122.

In the upright position, the positioning element 18 engages in the positioning hole 17. The positioning piece 18 is in clearance fit or transition fit with the positioning hole 17. For example, the positioning hole 17 and the positioning member 18 are each tapered, cylindrical, rectangular, or the like. The positioning accuracy between the first connecting portion 112 and the second connecting portion 122 can be improved and the shake between them can be reduced by the positioning member 18 and the positioning hole 17.

In one possible implementation, for example, the first connection portion 112 has a positioning member 18 and a protruding portion 15, and the second connection portion 122 has a positioning hole 17 and a through hole 16; at this time, the positioning member 18 is located on a side of the first connecting portion 112 near the first fixing portion 113, and the protruding portion 15 is located on a side of the first connecting portion 112 near the first fixing portion 113.

Referring to fig. 1, in some embodiments, at least one of the base 13, the first side plate 11, and the second side plate 12 has a water leakage hole 14. In the drawing, the base 13 has a water leakage hole 14. For another example, the first side plate 11 has water leakage holes 14. For another example, the second side plate 12 has water leakage holes 14. For another example, the base 13, the first side plate 11, and the second side plate 12 each have a water leakage hole 14. Wherein the number of water leakage holes 14 is plural. The water leakage holes 14 can be used for draining the accumulated water in the turnover box 1.
